Abstract

The author aims to show how the foundation of modern metaphysics took place. In order to achieve that, it will be crucial to understand the meaning of the first principle, which carries the entire metaphysical construction. The principle in question will be formulated as cogito ergo sum. It will be necessary to master the framework in which the principle appears because we are trying to talk about a complete project that has its meaning only in its entirety. In addition to the framework, the method that appears to be appropriate for metaphysics is also important - methodic doubt. Only through that method, we are able to reach an absolute position that should ensure everything else, because that method is radical enough. Finally, the meaning of the principle will be presented in its metaphysical sense. This will be emphasized all the time, but in the end, it will be briefly accentuated. Thus, we want to show the foundation of a new metaphysics, which should be founding everything else, including scientific knowledge.
